Thus the agricultural implenlent and also the lineotion of the traction may be controllec l by the: handles.

The ir al ne hlhas en arm 25 that :is pi v- ,otally connected tothe frame means of the pin26Q A pair of loge 27 ere pivotally QOIIHQOtBgd between QELIS 28 3 by means -of the m es 1 9 h d e t 27 ha e i eerwe'dl 1e lending lugs 30 that are -loeeted beneath :th wfi r e dlx extendin sfleng t iwd the top oft-the ,frame 517. The ai m 2,5 has a down terdly exte di g her tie "3 tha is located on the top of the flange 31. The flange 31 extends in the form of an are on opposite sides of the frame 17, the arc having a center in the vertical axis of the upwardly extending forward portion of the bar 16 and so that when the frame 1, together with the traction wheels '2 and the engine is moved angularly onthe forward end of the bar 16, the lugs 30 of the dogs 27 are moved beneath and along the flange 31 While the downwardly extending portion of the arm will rid-e on the upper surface of the flange 31, unless the dogs lock the arm 25 to the flange 31.

The dogs 27 are provided with a compression spring 33 that operates to press the upper ends of the dogs outwardly with respect to the pivot pins 29 and so as to cause the lugs 30 to clamp the flange 31 against the portion 32 ofthe arm 25. The lugs 30 .may be made cam'shaped and so as to grip the flange 31 when a force is applied to the frame 1 to swing it about the upwardly extending portion of the forward end of the bar 16. Such a force might be a ridge that one of the traction wheels would strike at an angle, or a stone or other obstacle that mightotherwise cause deflection in the direction of the draft of the traction wheels.

In order to change the direction of movement of the agricultural implement, one of the dogs 27 is released from 1ts engagement with the flange 31. The flange 31 can then be moved past the other dog but in a direction away from the dog that has been released and towards the other dog. The lugs 30 are normally held by the spring 33 at points that are well within the vertical planes passing through the axis of the pins 29 and the lug 30 of the dog 27 that is released will be swung to a point below and away from the under side of the flange 31. The arm 25 may then be moved toward that side of the agricultural implement on which the dog that has been released is located. Since the other dog 27 will move freely over the flange when the arm is moved in that direction. In order to release one or the other of the dogs 27 to permit lateral movement of the arm 25 to guide the agricultural implement, a sleeve 35 is pivotally connected to the arm 25 by means of the pin 36. The sleeve 35 extends through the downwardly extending portion 32 of the arm25, which is provided with an oblong slot 37 to permit lateral movement of the free end of the sleeve 35 within thatportion of the arm 25 and a pair of bolts 38 are located in the dogs 27 below their pivot pins 29 and so that their ends will contact against opposite sides of the sleeve 35. When the sleeve 35 is moved angularly with respect to the arm 25, it will press against one or the other of the ends of the bolts 38 and release the dog having that bolt from the flange 31. The plate'19, to which. the guide handles 18 are connected, has a bar 40 that extends into the end of the sleeve 35. The bar 40 is pivotally connected to the plate 19. Preferably the bar 40 is a Y-bar and the arms of the Y are pivo-tally connected to two points, axially in alignment, on'the plate 19, as at 41 and 42. If

desired, the end of the bar 40 may be provided with a ball 43, as indicated in Fig. 1. The ball 43 is also, preferably, the same size in diameter as the inner diameter of the sleeve 35 in order that there will be substantially a constant contact between the ball and the inner cylindrical surface of the sleeve when the angular relations, within the limitations of the structure, are changed, when guiding the agricultural implement.

' hen, therefore, itis desired to move the frame 1 angularly about the upwardly extending portion of the bar 16, the handles 18 are rotated in the frame 17 which operates to throw the bar 40 to one side since it is located well above the pivot pin 20; This operates to move the sleeve 35 laterally with respect to the arm 25 and releases one of the dogs 27. On continued rotation of the handles 18, the bar 40 pushes the army25 in the same direction that the sleeve 35 was moved and along the flange 31. This moves the frame 1 and the parts connected thereto, namely, the traction wheels 2 and the engine 4, angularly about the upwardly extending portion of the bar 16. This will cause the agricultural implement tobe drawn at an angle to the direction of its For convenience of operation, the clutch 7 if may be operated at a point remote from the engine 4, preferably at a point in close proximity to the handles of the agricultural implement. The clutch 7 may be operated by means of a yoke 44 that is supported on the upper end of the pivoted rod 45 that has an arm 46. The arm 46 is connected by a rod 47 to a pivoted handle 48 located on one of the handles 18 of the agricultural implement whereby the connection between the engine and the traction Wheels may be connected and disconnected.

Also, if desired, the frame 17 may be supported by a pair of wheels 50 that are supported in a frame 51, which are connected tothe frame 17 by suitable bars 52. The

agricultural implement, such as the cultivators 53, may be connected to plates 54 and the plates maybe adjustably connected to the frame 51 by means of the bolts 55 and the slotted arms 57 I claim: I 1. In an agricultural implement, a frame,
